hey.

one of our computers is having some issues. its been getting really slow
with really high loads. from top it appears as though there is enough free
ram/cpu, and that there shouldn't be any reason to have a load of 10+. i
was poking around in the logs and i found a lot of the following:


Sep 29 04:08:55 computername kernel: IN=eth0 OUT=eth0 SRC=136.142.89.250 DST=61.218.206.18 LEN=257 TOS=0x00 PREC=0x00 TTL=63 ID=53115 PROTO=UDP SPT=137 DPT=1025 LEN=237
Sep 30 11:53:29 computername kernel: IN=eth0 OUT=eth0 SRC=136.142.89.250 DST=218.16.125.85 LEN=48 TOS=0x00 PREC=0x00 TTL=63 ID=7854 DF PROTO=TCP SPT=4647 DPT=80 WINDOW=6432 RES=0x00 SYN URGP=0


they all seem to be originating from the same computer: 136.142.89.250 but
with different destinations. i believe this is output from iptables, which
is running on this computer to do nat for the lab.

can someone tell me what these mean?
